It's difficult to tell what you are asking. If the question is concerned with the bouyancy of the object, it will sink if it first displaces its volume of water, or will float if it first displaces its weight in water. Since density is mass per unit volume, objects with an average density greater than water will sink.
The density of an object that sinks is greater than the density of the liquid in which it sinks.
The shape of an object needs to be such that the overall density of the object is less than that of the medium in which it is placed
No, every object has a fixed density. if the density is less than water it will float. If not, it wont. Hope this answers your question!
The Density.
As an object sinks in a fluid the buoyant force on it would remain the same.
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
density!
Higher than what ?? If the object's density is higher than the density of water, then the object sinks in the water.
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
Ignoring shapes (using cubes), density (mass/volume) greater than "water" means it sinks. The floating object displaces its weight of the buoyant "object" (water, etc.)when it floats, but displaces its volume when it sinks.
if its in water and it has less grams per cm cubed than the water does then it will float and vicevesa
If the object's density is greater than the density of the fluid you put it in, then it sinks. If less, then it floats in that fluid.
